New Genesis [game, system, leveling]

"New Genesis" follows Dian Webb, a spirited and rebellious common soldier who refuses to conform to authority. When an otherworldly anomaly releases demons upon his city, Dian slays one of them, absorbing its soul and surviving its corruption before losing consciousness.

Upon awakening, Dian discovers he's trapped in a new realm where the absorbed demon's soul has transformed into a game-like system. With demons infesting this hostile land, Dian realizes he must embrace their strengths and harness his own abilities to return home. His perilous journey requires honing his skills, unlocking the system's potential, and manipulating demons, whether they be witches or god-like entities.
